LOCK N'UT.

Application filed January 18, 1924. Seral'lo. 687.118.

To @ZZ whom t may concern.'

Be it known that l, DANIEL OBRXEN, a citizen ot the United States, and a resident of Palestine, in the county oi' Anderson and State et Texaahave invented a new and Im-' proved'lxock Nut, of which the following a description. i

lilly/1 invention relates to lock nuts to be applied to ordinary' bolts for holding the nut immovable.

The prime object of my invention' is to i and the 'key -15 driven home, it'will be obvi provide a lock nut made in sections after the manner cfa split-nut, the one section having arms between which the other se@ tion is received, together with wedge means to tightly bind the sections on the bolt in a manner to prevent the displacement of thenut or a relative displacementof the nut sections. v y

Reference is to be had to the accompanying dra-wings forming a part of this specifi cation, it being understood that the drawings are merely illustrative Lot one example ot the invention.

vFigure y1 is a front view of a lock nutr embodying my invention, showing applied;

Figure 2 is a section on the line 2-2, Figure 1;

Figure 3 is a partly sectional front viev,1 of the separated elements of my improved lock nut.

lMv improved the same which is indicated at A.

The nut is given thegeneral form of a split nut being composed of similar sections 12, 13 adapted to meet at the median line of the nut. The lone section as 12 is formedl with parallel side arms 1li between which the other nut section 13 is snugly received. The said arms 14 are formed with holes 15 adapted to receive a key 16. The corre- L lock nut is applicable tov the threads 11 of any-ordinary bolt 10 for. uniting two parts, a fragment oi one of j l constitute it a split nut, one of the sections spondingwalls or sides 15a, 15b, or" the holes i 15 are preferably in the same inclined plane to conform Ato, the inclined side of the key which is wedge-shaped, the opposite side of the wedge or that side bearing against thc nut section 13 being parallel with the adjacent side of said nut section to. give a firm bearing against the latter. The key may be formed with a hole 17 to receive a cotter pin 18.

Viith the nut section placed on the bolt ons that the nut sections firmly bind against the bolt kto prevent a relative turning of the nut and bolt.

I would state in conclusion that While the illustrated example constitutes a prac`v vdeined vin the appended claim.y For example, the key 16 may be a tapered ork untapered cotter or ittmay have threads and a nut or other suitable device may be employed. lt will be observed that the key 16 is` driven from theright so that when driven into place the blow tends to tighten the nut lwhile a blow to dislodge thek key 16 tends to loosen the nut. f

lHaving thus described my invention, I

claim as new,` and desire to secure by Let-V ters Patent: I

A lock nut :termed in two sections to having arms between which the other sce- -tion ofthe nut is received, said arms having holes therein outside ot the secondnut section, and a wedge key receivable in said DANIEL 4oninnn,`
